Early Beginnings

In 1919, Herb Tautz started Delta Manufacturing Company in his garage. In 1923 he started manufacturing a small scrollsaw based on a design licensed from its inventor, Carl Moberg. The saws were sold through a subsidiary, Delta Specialty Co., and wore the "Delta Specialty Co." name.

In the late 1920s and into the early '30s, Delta rebadged a 12" bandsaw made by Heston & Anderson. Beginning in 1929, Tautz started identifying Delta Specialty Co. as "a subsidiary of Delta Manufacturing Co." In early 1932 the "Delta Specialty Co." name was dropped.

A Period of Ownership Changes and Acquisitions

In 1939, Tautz sold the company to a partnership consisting of Marshall Field, Charles G. Cushing, and H. Campbell Stuckeman; Tautz went on to run TAUCO Export Corp., which rebadged and sold Delta products overseas. The Delta name was difficult to trademark in other jursidictions so the Tauco name was used instead. We are uncertain of the ownership of Tauco and it is possible that it existed before the 1939 Marshall Field buyout.

In 1942, Marshall Field and partners sold it to Timken Detroit Axle Co., part of an early conglomerate controlled by Willard Rockwell. In 1945, Delta was sold to Rockwell Manufacturing Co., which had until very recently been known as the Pittsburgh Equitable Meter and Manufacturing Co., and which had just purchased Crescent Machine Co. In late 1945 or early '46, Rockwell bought Arcade Manufacturing Co.; although both Arcade and Rockwell/Delta had a "Homecraft" line of machinery, none of Arcade's Homecraft designs were ever sold by Rockwell/Delta; they did, however, use Arcade's foundry and machining facilities.

In 1948, Rockwell/Delta bought Red Star Products, Inc., makers of a line of turret-arm radial arm saws that competed well against DeWalt radial arm saws. It appears that the saws and their motors were manufactured for Rockwell by A. O. Smith Corp., which had already been making motors for Rockwell, and possibly for Delta before the purchase by Rockwell.

In 1953 Rockwell/Delta purchased the Callander Foundry and Manufacturing Co., a Canadian company that made the Beaver Power Tools line that dominated the Canadian hobbyist market. In 1960 they bought Porter-Cable Machine Co., maker of handheld power tools. In 1963 they bought Buckeye Tool Co., maker of pneumatic tools.

In the early 1970s, Delta manufactured the Penncraft machines for department store chain J. C. Penney.

The Rockwell International Years

In 1973, Rockwell Manufacturing Co. merged with North American Rockwell Corp., and the resulting operation was Rockwell International Corp. The former Callander Foundry continued to operated as Rockwell International of Canada, Ltd.

The Rockwell International era was marked by an emphasis on corporate financial performance and quality suffered on some products. In 1981, the line of handheld power tools was sold to Pentair Corp., which operated it as the Porter-Cable line—a name that had disappeared shortly after Rockwell had bought the Porter-Cable Machine Co. In 1984, Rockwell International sold the "machine tool" (woodworking and metalworking machinery) division to Pentair. Pentair operated it as the Delta International Machinery Corp., which included the Canadian operations.

The Pentair Years and Black & Decker

In the early '90s, Delta bough the Acme National subsidiary of R. A. Ness & Co.; their main product was an edge sander that remains the basis for Delta's edge sander. Also beginning in the early 1990s, Lindquist Machine corp. of Green Bay, Wisconsin, manufactured all of Delta's American-made drill presses, an arrangement that continued for about fifteen years. In 1995, Delta bought rip-fence maker Biesemeyer Manufacturing Corp. In the late 1990s, Pentair merged Delta's and Porter-Cable's manufacturing operations in Jackson, Tennessee. In 2000, the two divisions were formally merged.

On July 19, 2004, Black & Decker Corp. announced that it would purchase Pentair's power tools group, including the Porter-Cable, Delta, DeVilbiss Air Power, Oldham Saw, and FLEX brands. B&D already owned the DeWalt brand.

In January 2011, Stanley Black & Decker sold the Delta brand to a Taiwanese power tool manufacturer, Chang Type Industrial Co., Ltd., that was already manufacturing benchtop tools for them. The new company is Delta Power Equipment Corp. The CEO has said that the Delta products currently manufactured in the United States will continue to be made there.

Delta-branded Products from Other Makers

Delta mostly made their own products, but especially in the early years they sometimes OEM'd machines from other makers. For example, Delta's No. 385 12" bandsaw was manufactured by Heston & Anderson/Blue Star Products for Delta back in the late 1920s to early 1930s. And the Model 23-600 6" old-style bench grinder was made by Doerr Electric Corp.
